About Bay Area Spreadsheets

I've spent more than 45 years working with computers, business systems and real-world workflows — building tools, solving operational problems and helping people organize information more effectively.


That experience shapes the spreadsheets you'll find here. My focus is practical: clear layouts, useful calculations, editable designs and tools built around jobs people actually need to get done.


Some customers need a simple tracker. Others need a complete business-management system. Either way, the goal is the same: give you a spreadsheet that is useful without making the process unnecessarily complicated.


And if an existing product doesn't quite fit your workflow, customization help is available.

Need a Spreadsheet Customized for Your Needs?

Every spreadsheet is designed to be editable and customizable. File-specific requirements are listed on each product page.


If you need changes made for your workflow, business, or personal use, affordable customization services are also available.


Need a Spreadsheet Adjusted?

Most spreadsheets can be customized, and I can also help when you need something changed.

  • Minor adjustments: often available at little or no additional cost
  • Larger upgrades or custom work: quoted based on the requested scope

You'll know the cost before any custom work begins.
